Interpolation Method
Under real-time sampling, the oscilloscope acquires the discrete sample values of the
waveform being displayed. In general, a waveform of dots display type is very difficult to
observe. In order to increase the visibility of the signal, the digital oscilloscope usually
uses interpolation to “connect the dots” on the displayed waveform.
Interpolation is a processing method to “connect all the sampling points” to reconstruct an
accurate waveform, the interpolation method can fill out the gaps between points.
Press the
Acquire
button on the front panel to enter the ACQUIRE Function menu; then
press the
Interpolation
softkey to select
Sinx/x
or
X
.
X:
The adjacent sample points are directly connected on a straight line. This method
is only confined to rebuild on the edge of signals, such as square wave.
Sinx/x:
Connecting the sampling points with curves has better versatility. Sin(x)/x
interpolation method uses mathematical processing to calculate results in the actual
sample interval. This method more closely replicates more realistic shapes than pure
square waves and pulses. When the sampling rate is 3 to 5 times the bandwidth of
the signal, sinx/x is the recommended interpolation method.
